IMPROVED MODE OF SINKING WELL-TUBES.

Specification forming part of Letters Patent No. 50,142, dated September 26, 1865.

To all whom it may conce/rn:

Beit known that I, CHARLES W. KINNE, of Cortland, in the county of Cortland and State of New York, have invented a new and useful Improvement in Sinking Well-Tubes; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this specification.

Figure 1 is an elevation of inyimprovement in the act of driving into the earth; Fig. 2, a similar view, but with the tubing` in section and with the rod or bar forming the point driven down below the end ot' the tubing for the purpose of making a reservoir or cavity in the earth for the collection ofwater, Fig. 3, a view of the upper end of thecentr'al rod or bar.

Like letters of reference indicate corresponding parts in lall the figures.

Myimprovement belongs to that class where tubingis driven into the earth by positive force to form wells. Various devices for this purpose have been known. In one an openingpoint is simply attached to the lower end of the tubing,whicli is provided with perforations in the sides to admit water. In another the opening-point is provided with a perforated hollow shank extending up into the tubing, and when driven in place the tubing is raised suciently to expose the perforations; and in a third a rod or core is situated within the tubing, its lower end resting in a detached point and its upper end passing up to the top, the whole so arranged that after the tubing has been driven deep enough the point can be driven still deeper, so as to form a reservoir for the water to collect.

In principle my device resembles the last named, a rod or bar being employed within the tubing; but my invention consists in the particular construction and arrangement whereby the end ot' the central rod or bar itself forms the openingpoint and is capable of being adjusted downward so as to form a double wedge for opening the way, and whereby the adjusting collar or shoulder that holds the tubing in place at the top screws upon the end of the tubing, so that the screw-threads shall not become battered in driving.

In the accompanying drawings, A indicates the tubing; B, the central rod or bar, and O the adjustable shoulderat the top,which holds the tubing in place while being driven.

The tnbingA is of the ordinary arrangement, except that its lower end, a, is beveled downward or made sharp-edgedand is provided with slots b b, as clearly represented. The upper end has the usual screw-threads, c, for attaching the pump.

The interior rod or bar, B, extends from top to bottom, projecting above the tubing sufficiently to receive the blowsin driving. That portion d that rests in the body of and projects above the tubing is of a smaller diameter than the opening of the tubing itself, so that it can be easily withdrawn. I do not design that the tubing shall rest against or come in contact with it. Thelower end, s, however, which forms the opening-point, is iliade of a larger diameter a suitable length so as to lill the diameter of the opening of the tubing. The extremity is made pointed, so as to easily penetrate the earth.

The collar or shoulder O simply slides on the central rod or bar, B, and is secured to it at any desired position by means of a set-screw, g, which strikes into any ot a series of depressions or holes h h made vertically on the face of the rod. These holes prevent the collar from either sliding or turning, and therefore hold it steadily in place, notwithstanding the great strain to which it is subject in driving. The collar or shoulder is provided with a female screw, e, into which fastens the male screw c.

I claim no advantages resulting from the general use of the interior rod,-B, but only those which accrue from my particular construction and arrangement of it.

There are two principal features resulting from my construction:

First. The opening-pointfis thelower end of the rod itself and forms a part of it. Therefore its use is not limited to a single well, but it applies to many. As a matterot' economy this is of the utmost consequence. In all other de vices with which I am acquainted where the interior rod is employed its lower end rests iu a detached opening-point, which must remain in the well beneath the tubing. Thus a separate point is required with each well. I avoid this expense,for the samepointanswers as long as the rod lasts.

Second. I screw the collar G onto the end of thetubing at c, so as to prevent battering of the end of the tubing and the consequent injury of the screw-threads. This is necessary to properly attach the pump. In the devices before referred the collar simply rests above the end of the tubing, and in applying the force necessary to drive the tubing in place the end of the same becomes bruised. It will be seen that inasmuch as the threads are intermatched battering cannot ensue.

In addition to these primary advantages there are others of some consequence.

In Fig. 2 the pointfis shown as lowered at some distance below the end of the tubing. It' the whole is driven down into the earth in this position and the interior rod is then withdrawn, it will be seen that a cavity or reservoir will be formed beneath the tubing for the collection ot Water, and that without releasing the rod after the tubing is driven and driving still lower, as is the oase with other devices. Another advantage is, that the pointfand the bevel a form a double wedge at some distance apart, which it is apparent in philosophical principles will open the way much easier than if the whole wedge were combined in the single point. If desirable, however, the latter may be employed, as indicated by the black lilies in Fig. l. The slits b b, by giving some ilexibility to the end of the tubing, enable it to be driven with much greater ease. After the tubing has been driven in place the interior rod is removed by simply loosening the set-screw g and unsorewing the collar C from the end of the tubing, when the rod easily draws up.

I do not claim, broadly, the interior rod or bar, nor the collar; but

What I claim as my invention, and desire to secure by Letters Patent, is-

' 1. Forming the opening-pointf as a part of the interior rod, B, and using the same, in combination with the tubing A, in such a manner that a separate point for each well is dispensed with, substantially as herein set forth.

2. Coupling the adjustable collar C with the tubing A by means of l the screw-threads u e, and connecting the said collar with the interior rod, B, by means of the set-screw g and holes hy I1., the whole arranged substantially as herein specied, for the purpose of preventing the bruising ot' the end ot" the tubing and for retaining the saine in place.

3. The arrangement and combination as a whole7 consisting of the interior rod, B, with fixed point f, tubing A, with sharp-edged eX- tremity a, and the adjustable collar C, connected by the screw-threads a e, substantially as described.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses. l
